Built from just the disassembled hardware in a commercially-available PogoPlug mini-computer, a few tiny antennae, eight gigabytes of flash memory and some 3D-printed plastic casing, the F-BOMB serves as 3.5 by 4 by 1 inch spy computer. With a contract with DARPA, O’Connor has designed the cheap gadgets to be spy nodes, ready to be dropped from a drone, plugged inconspicuously into a wall socket, (one model impersonates a carbon monoxide detector) thrown over a barrier, or otherwise put into irretrievable positions to quietly collect data and send it back to the owner over any available Wifi network. O’Connor built his prototypes with gear that added up to just $46 each, so sacrificing one for a single use is affordable.
